Isn't this something what the diodes installed in parallel with the
relay coil are for, in transistor controlled circuits ? Somehow I feel
that diodes would be better solution.

Am I completely off the track here and would have fried my circuits by
removing this capacitor and installing diodes with relays ?

(Ok, in reality probably I would have both installed)
